A risk factor is anything that increases your chances of getting sick or having a problem. Risk factors for PMS include:
- A family history of PMS.
- Age. PMS becomes more common as women age through their 30s, and symptoms sometimes get worse over time.
- Anxiety, depression, or other mental health problems. This is a significant risk factor for premenstrual dysphoric disorder (PMDD).
- Lack of exercise.
- High stress.
- A diet low in vitamin B6, calcium, or magnesium.
- High caffeine intake.
